Is BOOTWAIT still used? (Was: kernel memory checks on boot vs. boot time)

Is BOOTWAIT still used? A quick grep in sys/boot shows nothing.

Digging history, BOOTWAIT never made its way from sys/i386/boot
to sys/boot/i386 and was removed in r58284 around 11y ago.
And more recently it disappeared from pc98, see r201342.
